Light weight headphone

Abstract

A light weight headphone insertable into a human ear canal having a curved portion leading to the ear drum. A main body element having a passageway through the main body element. An elongated hollow stem having two ends, one end attached to the passageway in the main body, the other end terminating in a handle. A speaker located in the handle and sound transmitted from the speaker through the hollow stem and the main body to the ear canal. The hollow stem member having a portion with a wavy configuration. Rotation of the hollow stem member will fit the hollow stem member around the curved portion in the human ear canal and seat the main body deeply in the ear canal to acoustically block the ear canal from outside noise and transmit the sound from the speaker in close proximity to the ear drum.

Description

BACKGROUND OF THE INVENTION[0001]This invention relates to light weight headphones (known as earphones or earbuds) for controlling sound from portable radio communications (i.e., Bluetooth, CD players, portable media players or mobile phones), to the eardrum and also, blocking sound to the eardrum from outside of the ear to maximize the clarity of the sound and minimize any damage to the eardrum. The present invention also relates generally to light weight headphones of the push-in type. Specifically, the present invention relates to a new concept for an insert light weight headphone including an insertion stem for a push-in type of light weight headphone that permits easy and deep insertion of the earplug portion of the light weight headphone with less pressure and less contact of the stem with the sidewalls of the ear canal. This light weight headphone will fit and provide comfortable and clear sound transfer to the eardrum to a larger number of individuals than prior art light we...

AI Technical Summary

Benefits of technology

[0017]The stem member has a crooked or wavy configuration as it extends outward from the main body element within the ear canal so that as the main body element of the light weight headphone is inserted into a user's ear canal the stem member may be rotated during insertion with the handle portion to fit around the typical curved portion in the human ear canal to seat the main body element to acoustically block the ear canal while at the same time spacing the stem member within the ear canal to minimize contact with the sidewalls of the ear canal. The crooked stem member may be either axially in line with the main body element or may be axially offset or eccentric along its length to increase the spacing effect during the rotation of the light weight headphone within the ear canal. The crooked stem member may include one or more portions that are angularly displaced from adjacent portions along the length of the stem member and with such angularly displaced adjacent stem portions being curved or straight within certain dimensional ranges to fit substantially the entire adult population.

[0018]In the present invention there is no need to bend the stem to insert the earplug. Just by twisting and/or pushing the handle portion of the stem member during the insertion, the user is able to find the best position for the stem to be spaced from the sidewalls in the typical curved portion of the human ear canal. The stem member within the ear canal has less contact with the walls of the ear canal (less pressure) because of the angularly displaced adjacent stem portions being curved or straight within certain dimensional ranges forming the crooked configuration. The curved or straight ang...

Problems solved by technology

A major problem generally incurred with all of these earplugs of the prior art resides in the anatomical fact that the human ear canal is quite variable in size and geometry.

As a result, a single type of a prior art earplug has not been found capable of accommodating the broad range of human ear canals in both size and geometry.

Quite often in inserting the earplugs of the prior art, the stem membe...
